Process for obtaining cyclic dicarbonic acids and their salts, by heating salts of other cyclic carbonic acids, under conditions already known, with which the initial salts are transformed into the salts of the carbonic acids that are desired, advantageously in the presence of catalysts, characterized in that a mixture of potassium or thallium salts and the sodium salts of the cyclic carbonic acids and of the reaction product is used, if appropriate by adding solvents, the salts are obtained, or by acidifying, the cyclic dicarboxylic acids free, conveniently.
